To all whom it may concern:

Be it known that I, ALBERT J. MEIER, a citizen of the United States, residing at Glendale, in the county of St. Louis and 5 State of Missouri, have invented certain new and useful Improvements in Concrete Construction, (Case A,) of which the following is a specification, reference being had therein to the acconipan ing drawings.

This invention re ates to concrete building structures and refers particularly to a construction in which concrete floor and ceiling members are supported by u rights orcolumns and are unlted integra y together. to form a rigid and unita structure.

It is the object of this invention to provide a concrete structure in which the reinforcing bars projectin from abutting, adjoining, or oppositelyisposed .members are united inte lly together.

In the rawlngs forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 isa plan view Fig. 2 is a sectional view on the line 2-2, Fig. 1 Fig. 3 is a plan view; and Fig. 4, is a fragmenta view 'artly in section, showi the relationship tweenthe'slabs and the earns.

In Figs. 1 and 2, a pair of beams 1 is depicted the. same being supported by a column Each of said beams 1 is preferably provided with the shoulders 3' and a tenon 4. A sset 5 or a. plurality of such gussets are ormed on column '2. Each gusset 5 is provided with a cut-away ortion 6 which communicates with a slot inr the end of a beam 1. A reinforcin bar 8 having its ends embedded in said co umn is adapted to project from said columnrinto slots 7 in each beam. Each tenon 4 is provided with a reinforcing bar or bars 9 which project from each end thereof. Each barf) pro ecting from the end of one of said tenons overlaps an end of a similar bar pro- 45 jecting from the other said tenon, and said overlapping ends are welded or brazed together electrically or in any other suitable manner, whereby said bars are united securely together and form a continuous bar;

art of said beam, and, adjacent the ends t ereof ,one or more of. said bars 10 a turn upwardly and project from beam 1., Each bar 10 projectingfrom the: end of one project from each slab into sai Reinforcing bars 10 are embedded in the bar projecting from tle' other said beam, and said overlapping ends are secured to gether by welding or brazing. Each cutaway portion 6 1s covsred by a 'so-called form (not shown in the drawings) and saidslots and cut away por ions are filled with grout or wet-concrete which is allowed to set therein and unites said beams and said that, when a slab is pla1 ed upon each shoul-' -der 3 of a beam 1, a :pace 13 above said tenon is left between the two slabs-sup orted by said beam.v Reil forcing bars 1 are embedded in said slab: 12 and those bars 14, which extend at at angle to s ace 13, space. Each bar l4 projecting from one of said slabs into space 13 overlaps a similar bar 14 projecting from an adjacent slab and said overlapping bars are :ecured together by welding or brazing, wl ereby said bars are made continuous and sa ad slabs are connected firmly together. G1 out or wet-concrete is poured into space 13 and, when set therein, unites said slabs and said beam to form a unitary structure.

In Fig. 3, the column 2 is surmounted b a cap 15 upon which flange 11 of each sla' 12 rests. The slabs 12 join each other without an intermediate spa :e for the formation of a beam, but cut-away parts 16 in each slab at the corner ad; acent a supporting column. unite to form a cruciform s ace partly over said cap 15 and partly wit an open. bottom, which nust be temporarily closed witha board or former. Reinforcing bars 17 extend into aaid'cruciform space from said slabs. Each bar 17 projecting from one of said slabs into said cruciform crete is pouredv into said cruciform space, and sets therein, being supnt rted while plastic by said cap and the board ir former'held under the bottomless part of s lid space, and unite the four slabs ling said cruciform lie of overlaps'zan-end ofa similar space and said column integrally 1 10- I claim: 1. A" concrete structure including a column forming a support, a plurality of mem other series at points over the support.

2. In a concrete structure, a support, a

plurality of slabs each having a portlon resting'on said support, said portions adjacent lies the support, and a serles of reinforcing bars carried by each slab and extending into said space, the bars of opposing slabs being in overlapping engagement and rigidly secured to each other whereby the respectegra-l one piece bars having portions of double thickness, which portions of double thickness are disposed in said space, and grout en aging the slabs and filling said space, an inclosing the exposed portions of the bars, the bars of the opposed slabs crossing each other. In testimony whereof I have affixed my signature in presence of two witnesses.
